Abstract

The magnitude of temperaturestructure coefficient is computed by sounderecho data. The results showed that the magnitude of has an obvious fluctuation with time. It has a character of positive bias distribution, and fits the logarithmic normal distribution. The analysis of the spectra showed that, the spectrum F(k) of usually fits the k−4 rule in stable and unstable stratifications. There exists a peak range of energy on the frequency range 10−1 − 3 × 10−4 s−1. The analysis of on time‐height counter section indicates that the distribution of Cr has horizontal stratum structure in stable stratification and it fits the rule in unstable stratification. These results measured by acoustic radar agree with earlier direct observations by airplanes [L. R. Tsvang, Radio Sci. 4(12) (1962)].
